Causes

VIPoma causes cells in the pancreas to produce a high level of a hormone called vasoactive intestinal peptide (VIP). This hormone increases secretions from the intestines. It also relaxes some of the smooth muscles in the gastrointestinal system.

The cause is not known.

VIPomas are often diagnosed in adults, most commonly at age 50. Women are more likely to be affected than men. This cancer is rare. Each year, only about 1 in 10 million people are diagnosed with a VIPoma.
